OTTO PRANTE AND AUGUST SCHMIDT, OF LANGERFELD, GERMANY.

LACE-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 618,815, dated January 31, 1899.

Application led November 4, 1898. Serial No. 695.470. (No model.)

To all whom t may concern.'

Be it known that we, OTTO PRANTE and AU- GUST SCHMIDT, subjects of the Emperor of Germany, residing at Langerfeld, near Barmen, Germany, have invented certain new and useful Improvements in Lace-Making Machines, of which the following is a specification.

Our invention belongs to that class of lacemaking machines in which the spindles of the bobbins are caused to travel in raceways by means of driving-disks which have recesses in their edges to engage the spindles and in which machines also the spindles are brought to rest at intervals and are then caused to resume their movement along the raceways after a certain period of rest or dwell. A machine of this character is described and shown in Letters Patent of theUnited States granted to Leon Louis Francois Malhere November l, 1808, No. 613,380.

Our invention relates particularly to the means for throwing the bobbin-spindles into and out of their traveling action along the raceways.

In the accompanying drawings, Figure 1 shows a plan view of a segment of a machine with parts in section and parts omitted. Fig. 2 is a sectional view on line 2 2 of Fig. 1. Fig. 3 is a similar view on line 3 3 of Fig. 1. Fig. 4 is a view similar to Fig. 2, showing the parts in a different position. Fig. 5 is a plan view of a section on line 5 5 of Fig. 3. Fig. 6 is a bottom plan view of a section on line 6 6 of Fig. 3. Fig. 7 is a plan view of the drivingdisks with their driving-gear and the arm for throwing vone of the disks into and out of connection with said gear. Fig. 8 is a plan view of the driving-gear with parts in section.

The machine comprises the top plate A, having raceways, as shown at X, of ordinary form, and a bottom plate B. Between these plates there are pillars a, upon which gearwheels CL are arranged to revolve and mesh with each other. These gears are driven in the ordinary way. (Not shown.) Drivingdisks b are arranged on the pillars close beneath the upper plate A, and these disks are connected by sleeves b and screws a2 with the gear-wheels a', so as to turn constantly therewith, and by reason of the adjacent gears meshing with each other the adjacent disks will turn in opposite directions.

These disks have semicircular notches h" in their peripheries to engage the spindles of the bobbins in order to move them valong the raceways. Switches e are employed to direct the spindles along the proper raceways in connection with the driving-disks b; but as said switches perform only their well-known functions it will not be necessary to describe their action in detail herein. As shown in Fig. 1, the sharp points of the raceways in line with the space between adjacent disks are partly cut away opposite the switches to afford stopping-places for the bobbin-spindles as they are moved thereto by the disks b. In order to release the bobbin-spindles from the disks, we employ stop-arms g, mounted upon the rods g2, which are guided to move vertically through the upper and lower plates A B and are moved downwardly by suitable pulls and upwardly by springs g3, according to thepattern of the lace to be formed. When the stop-arms g are in their upper positions, as shown in Fig. 2, the upwardly-proj ectin g stops g thereon will lie within the path of the spindles d, so that as the spindles are moved along the raceway by the disks they will engage the inner sides of the stops g' and will be arrested thereby, as shown on the right of Fig. 1. When the spindles d strike the stops, they aregradually released or withdrawn from the notches h" in the disks and they will remain at rest as long as the stop-arms g are in their elevated position and as long as the supplemental disks, now to be described, remain out of action, the operation of these parts being controlled by the pattern mechanism of ordinary form.

The supplemental driving disks C are mounted on the sleeves bx immediately below the main driving-disks b, and said supplemental disks have arms cx, adapted to engage the spindles d to move them from their positions of rest along the raceways, so as to be put into engagement with the main disks l). The supplemental disks have sleeves c", carrying splined thereto a collar O', having on its under face tappets C2 O3, as shown in bottom plan view, Fig. 6. These tappets are adapted when the collaris lowered to engage IOO with corresponding tappets @3664011 the upper Y gage the spindles and move them along the raceways to engage the main disks. For operating the collars C a fork f extends into a groove y of the collar, as shown in Fig. 3, the fork being carried by a rod f, movable vertically in guides of the upper and lower plates, each of said rods being operated downwardly by pulls controlled by the pattern mechanism and operated upwardly by springs f2. In order to prevent any undue movement of the supplemental disks, coiled springs f3, Fig. 6, are arranged about the rods f and have one end engaging the tappet of the collar. The stop-arms g are also guided by the depending pins e'.

We claim as our invention- In combination in a lace-making machine, the upper and lower plates A, B, the former having the raceways, the driving-disks b having notches to engage lthe spindles of the bobbins, the gear-wheels a connected with the disks b to rotate the same constantly, the stoparms g having the stops to engage the spindles, said stop-arms being moved vertically to place the stops into and out of the path of the spindles, the supplemental driving-disks C having arms to engage the spindles, the said disks being journaled about the sleeves of the main disks and held against vertical
